DavePhos as ligand efficiently promotes a palladium-catalyzed Heck reaction between 2-oxyacrylates and aryl bromides to provide 2-oxycinnamates, which serve as excellent precursors for the synthesis of monoaryl pyruvates or ortho ester-protected monoaryl pyruvates depending on the nature of the 2-oxy group.
